Review on H4 9003 HB2 LED Headlight Bulbs - 2020 Newest Super Bright 12000 Lumens 80W, 6000K Cool White 360 Degree Emitting Hi/Lo Beam Fog Light Replacement For Halogen by Earl Ton

I purchased this be installed in my 2014 Ford Flex, as the instructions indicate, I tested both light bulbs first before placing them in the unit. The first bulb I tried just placed the socket and the bulb together and checked both low and high beam LED worked fine, on the second one did the same and only one came on, I though this was because the socket was not secured with the bulb, I went ahead and tried to push it all the way in and applied a significant amount of force to push it all the way in but still didn't snap into place, I tried again with the first bulb and had the same problem. I had bought both headlight and fog lights (H-11) the same brand but since I wasn't planning to use LED's and incandescent combined I returned both. I have to say the H-11 did connect as supposed with the socket. I would not buy any products from this manufacturer.
